I noticed today that I can add a tag to my "favorite tag" list that does not yet exist. I then went to ask a question using that tag and was told I do not yet have enough rep to create new tags.

So my question is this:

If someone else creates that same tag, do I get any credit for coming up with it first (as shown by the fact that I listed it in my favorite tag list), or is the fact that it appears in my favorite list, even though it doesn't yet exist, just a placeholder for when it does.
